Final answer:
The statement is false; the "pinky finger" is connected to metacarpal number V, not metacarpal number I, which is the thumb.
Step-by-step explanation:
The statement that the "pinky finger" is known as metacarpal number I is false. The five metacarpal bones in the human hand are numbered 1 to 5, starting on the lateral (thumb) side. Therefore, metacarpal number I refers to the bone at the base of the thumb. The pinky finger is connected to metacarpal number V, which is the last metacarpal on the medial (little finger) side of the hand. The metacarpal bones are important components of hand structure, facilitating motion and strength for activities like gripping.
